Australia's Identified Mineral Resources 1993

In 1992-93 the value of mineral exports was $29 748 million, which was almost 63% of all commodity exports for that year.Australia's gold and base metal resources in the Economic Demonstrated Resources (EDR) category increased significantly in 1993. In contrast, diamond EDR decreased substantially for both industrial and gem categories, but subeconomic resources for both categories rose sharply. Other major commodities such as bauxite, black coal, brown coal, iron are, manganese ore, mineral sands and nickel had minor or no change in EDR.During the past year there were successful exploration programs at many known deposits and in greenfield regions. At a number of mines resources were increased progressively despite mining over an extended period.Mineral exploration expenditure in Australia rose marginally in 1992-93 to $631.8 million, indicating some recovery from the downward trend of the last four years. Gold continued to be the main exploration target, attracting 50.7% of the total 1992-93 expenditure.
